WebHow many moles of gas are in a volume of 42.4 L at STP? How many moles of gas are in a volume of 67.6 L at STP? How many moles of N2 gas occupies 5.20 L at 250 K and … WebWe know that at STP one mole of gas occupies 22.4 liters. And 11.2 liters is conveniently half of that. Therefore it would be half of mole. Now, we have to find out what is the mass of one mole of oxygen. The molar mass is equal to the atomic mass. Oxygen has an atomic mass of 16 grams. Since O2 contains two atoms, the molar mass of O2 is 32 grams.
Aim: How to convert from moles to volume and vice versa
